The cost of using a game facility is $1 for every 12 minutes. Talisa writes the function for the cost per hour as ()=. Explain T
Anna [14]

Using proportions, it is found that Talisa's error was at calculating the cost per minute of the game.

In the function:

  • The input is x, which is the number of minutes.
  • The output is f(x), which is the cost of playing the game for x minutes.

Talisa's expression is given by:

f(x) = 12x

The cost of using a game facility is <u>$1 for every 12 minutes</u>, hence, the cost per minute is:

c = \frac{1}{12}

And the correct expression for the cost is:

f(x) = \frac{x}{12}

Hence, it can be seen that Talisa's error was at calculating the cost per minute of the game.

If angle 0 is in quadrant I, what is the value of
Brilliant_brown [7]

Answer:

the \: answer \: is \: c \:  =  -  \frac{ \sqrt{14} }{5}

Step-by-step explanation:

\sin^{2}0 + ( \frac{ \sqrt{11} }{5} ) ^{2}  = 1( \sin^{2}0 +  \cos^{2} 0 = 1)

{ \sin }^{2}0 +  \frac{11}{25} = 1   \\  { \sin }^{2}0 =  \frac{14}{25}

\sin0_{1} =  -  \frac{ \sqrt{14}}{5} while \sin0_{2} =  \frac{ \sqrt{14} }{5}

  • Therfore theta is QI
  • Therfore sin theta >0
  • therefore \:  \sin0 =  \frac{ \sqrt{14} }{5}
